In general, the lattice energy tends to increase in a period. The lattice energy of NaCl, for example, is 788 kJ/mol, while that of MgCl2 is 1080 kJ/mol. This is due to the fact that the later bonds have a higher electrostatic force since the ions involved in the attraction are Mg...
You can see that much more energy is released when you make MgCl2 than when you make MgCl. Why is that? You need to put in more energy to ionise the magnesium to give a 2 ion, but a lot more energy is released as lattice enthalpy. That is because there are stronger ionic attraction...

Lattice Energy: The lattice energy of a compound is defined as the formation of gaseous ions from a solid ionic compound. It depends on the charge present on the ions and the size of the ions. Smaller the size and higher is the charge on ions, larger is the ...
Lattice Energy: Lattice energy is a term used for how strong the ions are attracted to each other within an ionic compound. The greater the distance between ions, the lesser is the lattice energy value because there are weaker forces of attraction...

For NaCl, the lattice dissociation enthalpy is 787 kJ mol-1. You should talk about 'lattice formation enthalpy' if you want to talk about the amount of energy released when a lattice is formed from its scattered gaseous ions. For NaCl, the lattice formation enthalpy is -787 kJ mol-1. ...
Lattice Energy:Lattice energy is the energy that is essential to isolate one mole of a solid ionic compound into the ions of gaseous and it is directly related to the force of attraction between oppositely charged particles.Answer and Explanation: ...
